PUMP.

Specification of Letters Patent.

Patented Nov. 21, 1905.

Application led February 15, 1905. Serial No. 245,692.

To all whom, it may concern:

Be it known that we, JOHN BRITTON FAL- LoURE and LESLIE MARSHALL ENGLISH, citizens of the United States, residing at Wheeling, in the county of Ohio and State of West Virginia, have invented new and useful Improvements in Pumps, of which the following is a specification.

This inventions relates especially to pumps for deep wells, such as oil-wells, and has reference to that type of pump employing a rigid pump-rod.

The primary object of the invention is an improved construction of this type of pump whereby the sucker may be removed and replaced without removing the pump-rod, and, furthermore, it is the object to provide for the application of the invention to deep well pumps now in use and without disturbing the stationary parts thereof.

A further object of the invention is to overcome the bending and yielding of the pumprods of deep-well pumps, and thereby prevent the lessening of the stroke of the sucker, which is due to this cause.

The invention consists in forming the pumprod hollow or tubular, so as to admit of the passage therethrough of the sucker, and in providing means whereby the sucker is adapted to be secured to and released from the pump-rod and raised therethrough.

The invention further consists in other novel features in the construction and arrangement of parts, all as hereinafter described and speciiically set forth in the appended claims.

In the accompanying drawings, Figure lis a vertical section taken through the complete pumpingapparatus and showing the hollow pumping-rod and sucker in operative position thereon. Fig. 2 is a vertical section showing a portion of the pump-tube and suction-barrel and also showing the pump-rod and sucker with its associated elements in the position necessary to effect the withdrawal of the sucker. Fig. 3 is a horizontal section taken on the line 3 3 of Fig. 1. Fig. 4 is an edge view of the frame-section forming an extension of the sucker-rod, in which is carried the stops for engaging the pump-rod.

The invention is illustrated in its application to the pumps of oil-wells, and in the drawings l designates the well-casing, and 2 the pump casing or tube, the latter being provided at its lower end with the pump-barrel 3, having the usual foot or check valve 4. This pumpbarrel is formed after the manner of those now in use, having the suction-bore 5 thereof ilared at the top to present inclined walls 6 to facilitate the entrance of the sucker 7, which walls terminate in an annular shoulder or seat 8, as it has been the purpose of the invention to utilize this form of construction in the manner to be clearly explained inorder to make ready adaptation of the invention to pumps already installed and without removing the pump-tube and its connected parts. As is usual, the pump-tube is provided with a cap 9, which forms the guide to the rod 10 that connects the pump-rod 11 with the pump-beam 12.

In the present instance the pump-rod 11 is tubular and of such size as to approximately fill the pump-tube and be guided in its movement and maintained against bending, this latter tendency being greatly overcome by the increased diameter of the rod. The bore of the pump-rod compensates for the space occupied by the rod in the pump-tube by being l kept in open relation at all times with the surrounding water-space, thus providing free passage of the water up through the pumprod and out at the openings 13 or through any other suitable exit.

The bore of the pump-rod 11 in the present instance is of a size to readily admit the passage therethrough ot' the sucker 7 and its sucker-rod 14, the latter being connected with a cable 15, by which it and the sucker are suspended from the top of the well and by means of which cable these parts are removed from the pump-tube. The sucker-rod includes an extension-frame 14, (shown detached in Fig. 4,) which extension comprises two parallel strips 14", secured together in spaced relation and forming, primarily, a nest or recess 16, in which is pivotally secured two folding plates 17, which extend in opposite directions and form a stop or abutment to engage the lower end of the pum p-rod when the sucker is in its normal position thereon, as shown in Eig. 1,

and in this position the sucker-rod is maintained by the cable 15, which is not only the means for raising and lowering the sucker, but the attaching means as well, and is connected to the pump-rod at the upper end thereof or, as shown, to the pump-beam in order that the cableand pump-rod will move together when in their assembled relations. In connecting the cable, as shown, the rod 10 is TOC made tubular to admit the cable, and in order to provide for the adjustment of the cable it is attached to a screw-threaded hook 18, supported in the adjusting-nut 19 on the beam 12 or in any other suitable manner.-

The folding stops 17 are each formed so as to present an upwardly-Haring edge 17a-from the under side thereof, providing thereby guiding edges which contact with the sides of the tubular pump-rod l1 and prevent any binding thereof within the rod during its passage therethrough in either direction. When within the pump-rod, the stop 17 will confine and clamp the spring 2O after the manner shown in Fig. Q, and upon passing out of the pumprod they will be forced apart by the tension of said springs and will assume their horizontal position, (shown in Fig. 1,) in which they rest upon the base of the recess in which they are mounted.

In Fig. 1 the pump-rod 11 is shown raised to the limit of its upward pumping stroke; but in making the application the pump-rod is maintained a sufcient distance above the limit of its upward stroke to bring the stops 17 far enough below the lower end of the rod to admit of the extension of the stops into their operative position, whereupon they are brought against the pump-rod by the lowering of said rod, and the cable is then made secure to maintain its combined operative relation.

For the removal of thelsucker the cable 15 is lowered to the point shown in Fig. 2, in which the stops 17 are folded, as shown in said figure, by contact of their guiding edges 17 with the wall of the mouth of the suctionbarrel 3, which is formed as in the general construction of pumps with a tapering wall 6.

With the stops nested, as shown in Fig. 2, by engagement with the wall 6, the pump-rod 11 is brought to rest at the limit of its downward stroke, and preferably, as shown, upon the shoulder or seat 8, the beveled edge 6 facilitating the guiding of the rod to its seat. This action brings the stops 17 within the pump-rod and the sucker, and its associated parts can then be drawn up through the rod by the cable and removed from the rod upon removing its end cap or coupling 11a and the cap 9 of the pump-tube.
